Comparing the Batch and Flow Syntheses of Metal Ammonium Phosphates: A Green Chemistry Approach [PDF]

open access: yes, 2021
Advanced materials are essential to the quality of modern day life, but the synthesis of these compounds is often inefficient in terms of energy, time and resources; especially when considering the hydrothermal batch methods used to prepare many such ...

Magnesium Contact Ions Stabilize the Tertiary Structure of Transfer RNA: Electrostatics Mapped by Two-Dimensional Infrared Spectra and Theoretical Simulations [PDF]

open access: yesJ. Phys. Chem. B 2021, 125, 740-747, 2021
Ions interacting with hydrated RNA play a central role in defining its secondary and tertiary structure. While spatial arrangements of ions, water molecules, and phosphate groups have been inferred from X-ray studies, the role of electrostatic and other noncovalent interactions in stabilizing compact folded RNA structures is not fully understood at the

Metal-Salen-based Probes for the Selective Detection of Phosphates via a Disassembly Approach

open access: yesCHIMIA, 2020
Polyoxophosphates are ubiquitous in nature and play important roles in biological systems and in the environment. Pyrophosphate (PPi), an important member of this family, is produced in over 200 biochemical reactions and is a marker in clinical diagnosis.
